The Company

Best known for their model lubricants, Labelle Industries is now owned by
Con-Cor, and is still selling their old N Scale engineer sets, along with a number
of odd, very dated items such as "Angle Hair" light bulbs (unless they just haven't bothered to remove them from their antiquated website).

The Figures

These are plastic figures sold in blister packs. Some have been branded for Con-Cor
and packed in baggies with header cards. Some packages are marked "Made in Western Germany." Still working on who made them for Labelle
(I'm betting it was
Preiser).
Photos are mine except for the Con-Cor branded item, which cropped up during a deep image search.
